[Northern Yellow-Spotted Monitors]

Town Common Conservation Park, Townsville, Australia, October 15, 2009

Another name is Argus Monitor. “Goanna” is frequently used in Australia as a generic term for monitor lizards.

These guys were engaged in a long struggle when we came across them. We watched for some time from the bus, at least 6 1/2 minutes, perhaps as long as 10. Eventually, one of them broke off and fled.
